What the Research Shows
Phase I clinical trial (n=11) evaluating Trametes versicolor (turkey tail) mushroom at escalating doses (3, 6, or 9 g/day) in women with breast cancer post-radiation. Turkey tail polysaccharopeptide (PSP) supplementation for 6 weeks significantly enhanced NK cell activity and increased CD8+ T-cell and CD19+ B-cell counts in a dose-dependent manner.

PSK (3 g/day) alongside chemotherapy significantly improved 5-year survival rates in gastric and colorectal cancer patients, mediated through beta-glucan activation of innate and adaptive immunity.
